Electrochemically anodized TiO2 nanotubes (TONTs) developed by constant voltage (60 V) or constant time (1 h) were prepared to investigate the morphological effect of TONTs for dye-sensitized solar cells. Under the constant voltage (60 V), the reaction time was varied from 20 min to 60 min, revealing that as the reaction time is increased, the length of TONT is increased from 1.26 μm (20 min) to 14.94 μm (60 min), respectively. In addition, under the constant time (1 h), the applied voltage was changed from 20 V to 60 V, showing that as the applied voltage is increased, the thickness of TONT is also increased from 4.28 μm (20 V) to 14.91 μm (60 V) with concurrently increasing the wall thickness and pore diameter. Based on these TONT films, photocurrent-voltage curves were achieved under illumination condition (AM 1.5, 100 mW/cm2). In general, the short-circuit photocurrent (Jsc) is steadily increased with the reaction time under the constant voltage, while the open-circuit voltage (Voc) is reversely reduced with the reaction time. Totally, the maximum efficiency (2.95 %) was obtained in the 600 min grown TONT film. In the similar context, the Jsc is increased with the applied voltage under the constant reaction time, while Voc is decreased, showing the maximum efficiency of 3.11 % at 50 V grown TONT film. Therefore, it was concluded that the effect of surface area is significantly important to improve the conversion efficiency.

본 연구에서는 ENIG, ENEPIG 의 Pad 표면처리가 고속전단시험에 미치는 영향에 대해 연구하고자 하였다. Pad의 표면처리를 ENIG와 ENEPIG로 하여 고속전단시험을 수행하여 그에 따른 Shear force와 Shear energy를 측정하였다. 고속전단시험결과 ENEPIG 표면처리 시편이 ENIG의 표면처리시편보다 shear force와 shear energy의 값이 높게 나타났다.
